The cup body 137 is connected to the upper end of the heating sheet 136, and the cup body 137 is located in the fifth limiting groove 1321. The cup body fixing ring 138 is connected between the cup body 137 and the atomizer base 132, and a fixing block 1381 is connected to the cup body fixing ring 138. The cup body fixing ring 138 can fix the cup body through the fixing block 1381, so as to prevent the cup body 137 from shaking easily inside the fifth limiting groove 1321.

[0075] Please refer to Figure 6 The heating cup assembly 13 further includes a temperature sensor 139. One end of the temperature sensor 139 is connected to the heating plate 136, and the other end of the temperature sensor 139 is connected to the atomizing base 131. The temperature sensor 139 can be used to control the temperature of the heating plate 136. The temperature sensor 139 is electrically connected to the main board 142 of the power supply assembly 14. The temperature sensor 139 can transmit the temperature information of the cup body 137 to the main board 142, so that the main board 142 controls the temperature of the heating plate 136. The temperature sensor 139 can control the temperature of the heating plate 136 through the main board 142, and the temperature control deviation of the temperature sensor 139 is small.

[0076] Please refer to Figure 4 , Figure 6 and Fig.23The heating cup assembly 13 also includes a heat-insulating silicone sleeve 1324, which is sleeved on the outer side of the upper end of the atomizer base 132. The heat-insulating silicone sleeve 1324 is connected to the atomizer base 132, and the heat-insulating silicone sleeve 1324 can insulate the atomizer base 132. The outer side of the heat-insulating silicone sleeve 1324 is connected with a plurality of third protrusions 13241, and the plurality of third protrusions 13241 are arranged circumferentially on the outer side of the heat-insulating silicone sleeve 1324, and the third protrusions 13241 can be used for anti-slip of the heat-insulating silicone sleeve 1324. The lower end of the inner side of the heat-insulating silicone sleeve 1324 is connected with an annular third groove 13242. The outer side of the atomizer base 132 is provided with an annular fourth protrusion 1323, and the third groove 13242 is connected to the fourth protrusion 1323. Because the heat-insulating silicone sleeve 1324 and the atomizer base 132 are connected via the third groove 13242 and the fourth protrusion 1323 , the heat-insulating silicone sleeve 1324 and the atomizer base 132 are connected more firmly.

[0077] Please refer to Figure 6 and Fig. 20 , the cup cover assembly 15 is connected to the upper end of the heating cup assembly 13, and the upper end of the cup cover assembly 15 is provided with an air guide hole 1511. The cup cover assembly 15 can be used to seal the heating cup assembly 13, so that when the heating cup assembly 13 heats the tobacco paste, the setting of the cup cover assembly 15 can prevent oil droplets from splashing and avoid the splashed high-temperature oil droplets from scalding the user's skin. Among them, the cup cover assembly 15 includes a ceramic pressure ring 153, a cover body 152, a silicone plug 151, a silicone hanging rope 154, and a silicone fixing ring 155. The ceramic pressure ring 153 is connected to the upper end of the heating cup assembly 13, and the ceramic pressure ring 153 insulates the heating cup assembly. The cover body 152 is detachably connected to the upper end of the ceramic pressure ring 153, and an airway 1521 is provided inside the cover body 152, and a first fixing groove 1522 is provided at the upper end of the airway 1521. The silicone plug 151 is set in the first fixing groove 1522, and the silicone plug 151 is connected to the cover body 152. Among them, the air guide hole 1511 is set on the silicone plug, and the air guide hole 1511 is connected to the airway. The lower end of the silicone plug 151 is connected to the third protrusion 1512, and the third protrusion 1512 is located between the two air guide holes 1511. The third protrusion 1512 can divert the gas. When the heating cup assembly 13 heats the tobacco paste, the third protrusion 1512 can divert the gas, and the heated gas can flow out effectively. Therefore, it is difficult for the heated gas to push the silicone plug 151 from the cover body 152, so that the connection between the cover body 152 and the silicone plug 151 is relatively stable.

[0078] Please refer to Figure 6 and Fig.21The silicone hanging rope 154 includes a first silicone ring 1541 and a second silicone ring 1542. The first silicone ring 1541 is connected to one end of the silicone hanging rope 154, and the second silicone ring 1542 is connected to the other end of the silicone hanging rope 154. The first silicone ring 1541 is sleeved on the cover 152. Since the material of the first silicone ring 154 is elastic, the first silicone ring 1541 is connected to the cover 152 by interference, and the connection between the first silicone ring 1541 and the cover 152 is relatively stable. The second silicone ring 1542 is sleeved on the heating cup assembly 13. Since the material of the second silicone ring 1542 is elastic, the second silicone ring 1542 is connected to the heating cup assembly 13 by interference, and the connection between the second silicone ring 1542 and the heating cup assembly 13 is relatively stable. When the user opens the cover 152, because one end of the silicone hanging rope 154 is connected to the cover 152, and the other end of the silicone hanging rope 154 is connected to the heating cup assembly 13, the cover 152 is not easy to fall off.

[0079] exist Figure 6 Based on Fig. 22 and Fig.24 . A first protrusion 1531 is connected to the lower end of the ceramic pressure ring 153, and a first groove 1371 is provided at the upper end of the cup body 137. The first protrusion 1531 and the first groove 1371 are detachably connected. When there is residual tobacco paste or impurities in the cup body 137, it is convenient for the user to disassemble the cup body 137, so that the user can clean the cup body 137. A second groove 1532 is provided on the outer periphery of the ceramic pressure ring 153, and a silicone fixing ring 155 is connected to the second groove 1532. The material of the silicone fixing ring 155 is an elastic material. Because the silicone fixing ring 155 is connected between the ceramic pressure ring 153 and the heating cup assembly 137, it is difficult for a gap to exist between the ceramic pressure ring 153 and the heating cup assembly 13, and the ceramic pressure ring 153 and the heating cup assembly 13 are more firmly connected.

[0080] Please refer to Figure 8 and Fig. 9 , the glass cigarette holder 12 is connected to the upper end of the shell 11. The glass cigarette holder 12 is connected to the heating cup assembly 13, and the glass cigarette holder 12 can be used to guide out the smoke. Among them, the glass cigarette holder 12 is a three-layer glass tube structure, and the glass cigarette holder 14 includes a first glass tube 121, a second glass tube 122, and a third glass tube 123. The first glass tube 121 is a cylindrical hollow structure, and the bottom end of the first glass tube 121 is provided with an air inlet 1211, and the air inlet 1211 can guide the smoke into the first glass tube 121. The upper end of the first glass tube 121 is provided with a first air outlet 1212, and the first air outlet 1212 is used to guide the smoke from the first glass tube 121.

[0081] Please refer to Figure 8 and Fig. 9The second glass tube 122 is a conical hollow structure. The second glass tube 122 is wrapped around the outside of the first glass tube 121, and the second glass tube 122 is connected to the first glass tube 121. The upper end of the second glass tube 122 is a sealed structure. The lower end of the second glass tube 122 is provided with a second air outlet 1221, and the second air outlet 1221 is used to guide the smoke out of the second glass tube 122.

[0082] Please refer to Figure 8 and Fig. 9 The third glass tube 123 is a conical hollow structure, and the third glass tube 123 is wrapped around the outer side of the second glass tube 122. The third glass tube 123 is connected to the second glass tube 122, and a third gas outlet 1231 is provided at the upper end of the third glass tube 123, and the third gas outlet 1231 can guide the smoke out of the third glass tube 123.

[0083] Please refer to Figure 8 and Fig. 9 Because the second glass tube 122 and the third glass tube 123 are both conical structures, smoke is easier to gather inside the second glass tube 122 and the third glass tube 123. Therefore, when the user inhales smoke through the third glass tube 123, smoke is not likely to leak into the external environment in large quantities. The third air outlet 1231 is elliptical, and when the user inhales smoke, the glass mouthpiece 12 can fit the mouth, and the user's mouth can wrap the glass mouthpiece 12 more tightly. Therefore, the glass mouthpiece 12 can form a seal with the mouth, and the design of the glass mouthpiece 12 is more ergonomic.

[0084] Please refer to Figure 8 and Fig. 9 , the smoke is first introduced into the first glass tube 121 from the air inlet 1211 at the lower end of the first glass tube 121, and the smoke is introduced into the second glass tube 122 from the first air outlet 1212 at the upper end of the first glass tube 121. Then, the smoke is introduced into the third glass tube 123 from the second air outlet 1221 at the lower end of the second glass tube 122. Subsequently, the smoke is exported from the third air outlet 1231 at the upper end of the third glass tube 123. Since a large amount of smoke leaking into the surrounding environment is likely to have an adverse effect on the surrounding people, the structural design of the glass cigarette holder 12 can avoid exporting the smoke in a straight line, and the glass cigarette holder 12 can slow down the export speed of the smoke. When the user inhales smoke through the third glass tube 123, the smoke is not easy to leak into the external environment in large quantities. Among them, the first glass tube 121 and the second glass tube 122 are integrally formed. It is difficult for a gap to exist between the first glass tube 121 and the second glass tube 122, so that the first glass tube 121 and the second glass tube 122 are firmly connected. The second glass tube 122 and the third glass tube 123 are integrally formed, and there is hardly any gap between the third glass tube 123 and the second glass tube 122 , so that the third glass tube 123 and the second glass tube 122 are firmly connected.

[0085] Please refer to Figure 3 and Figure 6 , the power supply assembly 14 is connected to the inside of the shell 11, and the power supply assembly 14 can be used to supply power to the heating cup assembly 13. Among them, the power supply assembly 14 is connected to the inside of the plastic shell 111, and the power supply assembly 14 includes a battery 141, a mainboard 142, a charging connector 144, a battery holder 145, and a wireless charging assembly 146. The wireless charging assembly 146 is connected to the lower end of the inside of the plastic shell 111, and the mainboard 142 is connected to the upper end of the wireless charging assembly 146. The wireless charging assembly 146 is electrically connected to the battery protection board 143, and the wireless charging assembly 146 can wirelessly charge the battery 141. The mainboard 142 is electrically connected to the battery protection board 143, and the battery holder 145 is connected to the upper end of the mainboard, and the battery holder 145 is also connected to the plastic shell 111. The battery 141 is connected to the upper end of the battery holder 145, and the battery 141 is electrically connected to the battery protection board 143. The charging connector 144 is connected to the inner side of the side wall of the plastic housing 111 , and the charging connector 144 is electrically connected to the mainboard 142 .

[0086] exist Figure 6 and Fig.10 Based on Fig.11 and Fig.12 The aerosol generating device 10 includes an atomizer bracket 18, and the atomizer bracket 18 is connected to the lower end of the atomizing silicone seat 1315 of the heating cup assembly 13. One end of the atomizer bracket 18 is provided with a first connecting surface, and the other end of the atomizer bracket 18 is provided with a second connecting surface 18111. The lower end of the heating cup assembly 13 is connected with a first protrusion 1313 and a second protrusion 1314, and the first protrusion 1313 and the second protrusion 1314 are both provided at the lower end of the atomizing base 131.

[0087] Please refer to Figure 6 , Fig.11 and Fig.12 The atomizer bracket 18 includes a receiving portion 182 and a supporting portion 181 connected to each other. A third receiving groove 1821 is provided in the middle of the receiving portion 182, and the third receiving groove 1821 can be used to receive the display light 19. The first connecting surface 18111 is provided at one end of the supporting portion 181, and the second connecting surface 18122 is provided at the other end of the supporting portion 181. The first connecting surface 18111 is fixedly connected to the first protrusion 1313, and the second connecting surface 18121 is fixedly connected to the second protrusion 1314. The heating cup assembly 13 is fixedly connected to the atomizer bracket 18 through the protrusion, so that the user does not need to drill a screw hole at the bottom of the heating cup assembly 13 to fix the heating cup assembly 13. Therefore, the setting of the atomizer bracket 18 can better form a seal for the heating cup assembly 13, avoid the risk of oil leakage and air leakage of the heating cup assembly 13, and the atomizer bracket 18 can better fix and seal the heating cup assembly 13 at the same time.

[0088] Please refer to Figure 6 , Fig.11 and Fig.12 The support portion 181 includes a first support member 1811 and a second support member 1812 that are arranged opposite to each other. The first support member 1811 and the second support member 1812 are both connected to the accommodating portion 182, the first connection surface is located at one end of the first support member, and the second connection surface 18121 is located at one end of the second support member 1812. A first support surface 18112 is provided at the upper end of the first support member 1811, and a second support surface 18122 is provided at the upper end of the second support member 1812. The first support surface 18112 and the second support surface 18122 are both connected to the heating cup assembly 13, and the first support member 1811 and the second support member 1812 can better support and limit the heating cup assembly 13. Since the first support member 1811 and the second support member 1812 can limit the heating cup assembly 13, the position of the heating cup assembly 13 is better fixed. Therefore, it is difficult for a gap to exist between the heating cup assembly 13 and the first support member 1811 and the second support member 1812, so that the space utilization rate of the aerosol generating device 10 is high. In addition, it is difficult for the heating cup assembly 13 to loosen on the support portion 181, and the heating cup assembly 13 can be more firmly connected to the support portion 181.

[0089] Please refer to Figure 6 , Fig.11 and Fig.12 The support part 181 also includes a connecting member 1813, which is groove-shaped. The connecting member 1813 is connected between the first supporting member 1811 and the second supporting member 1812, and a third supporting surface 18131 is provided at the upper end of the connecting member 1813. The third supporting surface 18131 is connected to the heating cup assembly 13, and the connecting member 1813 can increase the strength of the supporting member. The connecting member 183 can provide a supporting force to the first supporting member 1811 and the second supporting member 1812, so that during the long-term use of the atomizer bracket 18, the first supporting member 181 and the second supporting member 182 are also difficult to be damaged.

[0090] Please refer to Figure 3 , Figure 6 and Fig.13 The upper end of the plastic housing 111 is provided with a second through hole 1118, and the aerosol generating device 10 further includes a temperature indicator light 175 and a glass fixing seat 17. The temperature indicator light 175 is connected to the inside of the plastic housing 111, and the temperature indicator light 175 is located at the lower end of the second through hole 1118. The temperature indicator light 175 can be used to indicate whether the aerosol generating device 10 is working at a normal temperature.

[0091] Please refer to Figure 3 and Figure 7, the glass fixing seat 17 is cylindrical, and the glass fixing seat 17 is arranged at the upper end of the second through hole 1118. The glass fixing seat 17 is connected to the plastic shell 111, and a fourth accommodating groove 1123 is arranged in the middle of the zinc-plated upper shell 112, and the glass fixing seat 17 is arranged in the fourth accommodating groove 1123. The glass fixing seat 17 includes a light-transmitting portion 171 and a light-shielding portion 172 connected to each other, and the light-transmitting portion 171 is a translucent structure. The light-transmitting portion 171 and the light-shielding portion 172 form a fourth fixing groove 173, and the fourth fixing groove 173 is connected to the glass cigarette holder 12, and the fourth fixing groove 173 can be used to fix the glass cigarette holder 12. The light-transmitting portion 171 is located in the middle of the bottom end of the glass fixing seat 17, and the light-transmitting portion 171 can transmit the light emitted by the temperature indicator light 175. The light-shielding portion 172 is arranged along the circumference of the light-transmitting portion 171, and the light-shielding portion 172 can block the light emitted by the temperature indicator light 175. The light shielding portion 172 is an elastic structure, and a fourth groove 1721 is provided on the light shielding portion 172. A fifth protrusion 1124 is connected to the inner side of the side wall of the fourth accommodating groove 1123, and the fifth protrusion 1124 is interference-connected with the fourth groove 1721. Because the glass fixing seat 17 and the zinc-gold-plated upper shell 112 are connected through the fourth groove 1122 and the fifth protrusion 1124, the glass fixing seat 17 and the zinc-gold-plated upper shell 112 are connected more firmly.

[0092] Please refer to Figure 3 and Figure 7, the light emitted by the temperature indicator light 175 can be transmitted from the light-transmitting portion 171, and the temperature indicator light 175 can indicate whether the aerosol generating device 10 is working at a normal temperature, so that the user can use the electronic atomizer 10 more safely, and the light-shielding portion 172 can block the light emitted by the temperature indicator light 175, so that the light emitted by the temperature indicator light 175 can be more concentrated on the light-transmitting portion 171, and the light emitted by the temperature indicator light 175 is more obvious in the light-transmitting portion 171, and the user can more easily observe the indication of the temperature indicator light 175. Among them, when the temperature indicator light 175 is in a flashing state, the aerosol generating device 10 is not working at a normal temperature. The user cannot use the aerosol generating device 10, and it is more dangerous for the user to use the aerosol generating device 10 at this time. When the temperature indicator light 175 is in a constant light state, the aerosol generating device 10 is working at a normal temperature, and the user can use the aerosol generating device 10. The light-shielding portion 172 can block the light emitted by the temperature indicator light 175, so that the light emitted by the temperature indicator light 175 can be more concentrated on the light-transmitting portion 171. Therefore, the light emitted by the temperature indicator light 175 is more obvious in the light-transmitting portion 171, and the user can more easily observe the indication of the temperature indicator light 175. The glass mouthpiece 12 is a transparent structure, and the light emitted by the temperature indicator light 175 can be transmitted to the glass mouthpiece 12 through the glass fixing seat 17 and the plastic support plate 116 at the upper end of the plastic shell 111. The glass mouthpiece 12 can display the light emitted by the temperature indicator light 175, so that the user can more conveniently understand whether the aerosol generating device 10 is working at a normal temperature.

[0093] Please refer to Figure 3 , Figure 4 and Figure 6The aerosol generating device 10 further includes an air guide tube 16 and a cushion block 174. One end of the air guide tube 16 is connected to the glass cigarette holder 12 through the glass fixing seat 17, and the other end of the air guide tube 16 is connected to the heating cup assembly 13, so that the glass cigarette holder 12 is connected to the heating cup assembly 13. The silicone member 161 is connected to one end of the air guide tube 16, and the silicone member 161 is close to the glass cigarette holder 12. The silicone member 161 and the stainless steel air guide tube 16 work together to form a one-way valve system. When the user inhales through the glass cigarette holder 12, the silicone member 161 will be pushed open along the air guide tube toward the direction of the glass cigarette holder 12, so that the air guide tube 16 can guide the smoke from the heating cup assembly 13 to the glass cigarette holder 12, and the user can inhale the smoke through the glass cigarette holder 12. On the contrary, when the user blows air through the glass mouthpiece 12, the silicone member 161 will be close to the air duct 16, so that the airflow between the glass mouthpiece 12 and the heating cup assembly 13 cannot circulate, so the moisture inside the glass mouthpiece 12 will not flow into the heating cup assembly 13, which can avoid the risk of short circuit caused by water ingress to the heating cup assembly 13. The pad 174 is connected between the temperature indicator light 175 and the battery 141, and the material of the pad 18 is EVA. EVA is ethylene-vinyl acetate copolymer, and the setting of the pad 18 can prevent the battery 141 and the temperature indicator light 175 from being easily loosened. The aerosol generating device 10 also includes a display light 19, which is connected to the atomizer bracket 18. The display light is electrically connected to the main board 142, and the on and off of the display light 19 can indicate the opening and closing of the aerosol generating device 10. The display light 19 is on, indicating that the aerosol generating device 10 is turned on, and the display light is off, indicating that the aerosol generating device 10 is turned off. The display light 19 includes a display light board 191, a lamp bead silicone sleeve 192, and a display light plastic board 193.

[0094] The working principle of the present invention is as follows: when the user uses the aerosol generating device 10, the user first opens the cover 152 of the glass cover assembly 15. Because one end of the silicone hanging rope 154 is sleeved on the cover 152, and the other end of the silicone hanging rope 154 is sleeved on the heating cup assembly 13, the cover 152 is not easy to fall off. The user puts the tobacco paste into the cup body 137 of the heating cup assembly 13, and then the user closes the cover 152, at which time the cover 152 is connected to the ceramic pressure ring 153. In order to facilitate the disassembly of the cup body 137, the cup body 137 and the ceramic pressure ring 153 are detachably connected through the first protrusion 1531 and the first groove 1371. The user turns on the aerosol generating device 10 through the button 147, and the button 147 is connected to the first through hole 1114 on the side wall of the plastic shell 111. In order to ensure that the heating cup assembly 13 is firmly connected to the outer shell 11 and the heating cup assembly 13 has good sealing performance, the heating cup assembly 13 is connected to the first connecting surface 18111 and the second connecting surface 18121 of the atomizer bracket 18 through the first protrusion 1313 and the second protrusion 1314, and the atomizer bracket 18 is connected to the zinc-plated upper shell 112 of the outer shell 11.

[0095] At this time, the power supply assembly 14 can supply power to the heating plate 136 through the battery protection board 143 and the upper electrode 1341 and the lower electrode 1342, and the power supply assembly 14 can supply power to the temperature sensor 139 through the wire. In order to firmly connect the battery protection board 143 to the plastic shell 111, one end of the battery protection board 143 is connected to the first limiting groove 11113 of the plastic shell 111, and the other end of the battery protection board 143 is connected to the second limiting groove 11123 of the plastic shell 111. The power supply assembly 14 can supply power to the display light 19 through the wire, so that the display light 19 is in a constantly lit state. The upper electrode 1341 is located in the second fixing groove 13311 of the electrode fixing seat 1331, and the lower electrode 1342 is located in the third fixing groove 13321 of the electrode insulating seat 1332.

[0096] Subsequently, the heating sheet 136 heats the cup body 137, and at the same time, air can enter the heating cup assembly 13 from the air guide hole 1511 of the silicone plug 151 and the airway 1521 of the cover body 152, so that the heating cup assembly 13 can atomize the tobacco paste into tobacco. The ceramic insulation seat 135 at the upper end of the electrode fixing assembly 133 can insulate the cup body 137 to prevent the temperature of the cover body 152 from being too high. After the heating sheet 136 heats the cup body 137, the light emitted by the temperature indicator light is transmitted to the transparent glass mouthpiece 12 through the plastic support plate 116 and the light-transmitting portion 171 of the glass fixing seat 17. The user can identify whether the aerosol generating device 10 is working at a normal temperature through the light emitted by the temperature indicator light 175. In order for the user to easily observe the indication of the temperature indicator light 175, the glass fixing seat 17 blocks the light emitted by the temperature indicator light 175 through the light shielding portion 172.

[0097] Afterwards, the user inhales the air in the glass mouthpiece 12, and the smoke enters the glass mouthpiece 12 from the heating cup assembly 13 through the air guide tube 16. The smoke enters the first glass tube 121 from the air inlet 1211 at the lower end of the first glass tube 121, and the smoke enters the second glass tube 122 from the first air outlet 1212 at the upper end of the first glass tube 121. Then, the smoke enters the third glass tube 123 from the second air outlet 1221 at the lower end of the second glass tube 122. Subsequently, the smoke is discharged from the third air outlet 1231 at the upper end of the third glass tube 123, and the user can inhale the smoke, and the user completes the use of the aerosol generating device 10.

[0098] The present invention provides an aerosol generating device 10, which includes a housing 11, a heating cup assembly 13, a cup cover assembly 15, a glass cigarette holder 12, and a power supply assembly 14. One end of the heating cup assembly 13 is connected to the inside of the housing 11, and the other end of the heating cup assembly 13 protrudes from the housing 11. The heating cup assembly 13 is used to atomize the tobacco paste into smoke. The cup cover assembly 15 is connected to the upper end of the heating cup assembly 13, and the upper end of the cup cover assembly 15 is provided with an air guide hole 151. The glass cigarette holder 12 is connected to the upper end of the housing 11, and the glass cigarette holder 12 is connected to the heating cup assembly 13. The glass cigarette holder 12 can be used to guide the smoke, so that the user can easily inhale the smoke through the glass cigarette holder 12. The power supply assembly 14 is connected to the inside of the housing 11, and the power supply assembly 14 can supply power to the heating cup assembly 13.
